As a teenager who lived in a small town, I became obsessed with travel, collecting piles of books written by authors who'd traversed the globe under their own steam. I vowed to do the same and got a job at a bookshop to pay for it. There's nothing like working all hours to make you appreciate money, and I vowed not to waste a cent when I did get to see the world.
